Hi All I have a raster layer of 8 bit RGB orthophoto with the source data as GeoTiff tiles (tile index) . Some of the source images have the nodata (0,0,0) defined in the metadata some do not. Can MS automatically determine the nodata and use that as a transparency for each image in the tile index?
The issue that I am having is that I have a large coverage area that is composed of RGB tiled uncompressed geotiffs with real nodata values at the edges of the coverage and tiles on the interior of the coverage are RGB tiled compressed ycbcr geotiffs with no nodata defined. If I use the OFFSITE 0,0,0 parameter in my mapfile the resultant images will have holes on the interior of the image (). I have tried scaling the images however it appears that JPEG compressed YCBCR images do not scale well Regards _______________________________________________ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
